CockroachDB support for `migrate diff` and `dev-url`

I'm using atlas with ent and CockroachDB. It's been working fine so far using a postgis image as --dev-url when generating migrations like such:

atlas migrate diff $(name) \
    --dir "file://ent/migrate/migrations" \
    --to "ent://ent/schema" \
    --dev-url "docker://postgis/postgis/15-3.4/app?search_path=public"

However, I need to use a feature that is only supported by CRDB: Row-Level TTL.

I generated a custom migration that looks like:

ALTER TABLE my_table SET (ttl_expiration_expression = 'expires_at');

This obviously can't be handled by postgres, and as far as I can tell docker://cockroachdb/cockroach isn't supported in --dev-url. I attempted to set up and run a local image to generate the diff like so:

atlas migrate diff $(name) \
        --dir "file://ent/migrate/migrations" \
        --to "ent://ent/schema" \
        --dev-url "postgres://dev@127.0.0.1:26257/app?search_path=public&sslmode=disable"

However, when running the above I hit an error (the database is clean to start with and then all existing schema is loaded before erroring):

Error: sql/migrate: taking database snapshot: sql/migrate: connected database is not clean: found table "my_table" in connected schema
